METALLIC BONDING FOR CONCRETE'SUPPOBTS.

Application mea February 9, 1927. sum1 No. 167,606.

This invention relates to improvements in metallic bonding structure for reinforcing concrete supports, such as foundations for heavy buildings and mine pillars subjected 6 to excessive crushing strains from overhead loads and also bulkheads employedg in mine caisson and subway construction to withstand heavy lateral pressure. It is customary to construct such supports of concrete re-v l0 inforced by a metallic skeleton or retaining casing, the concrete providing the bulk and the skeleton or casing imparting the required stability. The object of the instant invention is to provide a metallic casinllr l supports, formed of heavy units tliaving an interlock that facilitates ready assembly of the parts in a composite whole, the casing so formed providing an efficient reinforcement and container for the concrete. The invention is described in detail hereinafter, illustrated by the accompanying drawings and delined in the appended claims.

In the drawings, in which similar characters designate corresponding parts:

Figure 1 is a side elevation of a cubical support of reinforced concrete embodying the invention, said support may be a mine pillar or a foundation for a structural column.

Fi res 7 to 10, inclusive, are detail perspectwe views of the several structural units employed in the construction of the reinforcement.

Figure 11 is a detail view showing the joint of two units in oblique relation.

Figures 12 and 13 are diagrammatic views, res ectively showing an elevation and a plan of bulkhead embodying the invention.

Referrin to the drawings in detail, 15, 16, 17 and 18 esig'nate several structural units employed in the construction of a mine pillar or column support. The units 16 and 17 are alike in formation, but the two are shown with dilerent reference 'characters to desigfor such and between each pair of nate similar parts; the purpose of this is to facilitate the description of the assembled parts. The several units are made of channel iron, mainly of H-shape section, and have their ilanges notched and recessed at the ends to provide a mutual interlock. The unit 15 shown in part in Fig. 7 is a base member, comprising an iron with a single channel and a flat base. In each end of this member, in the flanges thereof, are the notches 14 extending to the web 19 of the iron. The outer edges of the flanges are cut away to a slight ,depth between the notches 18, as at 20. u

The unit 16, shown in Fig. 8, is' an iron channeled on opposite sides to form an H- shape section and in the flanges at each end and on one side are the notches 22 cut through the flanges to the web 23. The flanges between the notches at 'each end of the iron are slightly cut away as at 24. The flanges on the other side of the iron are recessed at their ends, as at 25, opposite to the notches 22. The unit 17, as shown in Fig. 9, is also an iron channeled on opposite sides to form an H-shape section, the ilanges on one side of which areprovided at their ends with notches 26 that extend to the web 27, notches the flange 1s cut away, as at 28. The flanges on the other side of the iron are slightly recessed, as at 29, opposite to the notches 26. The unit 18, one end of which is shown in Fig. 10, is an iron channeled on but one side and in the' ends of its flanges are the shallow rccesses 30.

In the construction of a foundation pier or mine pillar, as illustrated in Fig. 1-5, on a prepared level surface are placed twoI of the units 15, which may b e termed base units, in parallel relation with their flanged 4`sides upward. Then across the opposite ends of these base units are placed a pair of the intermediate units 16. In the mutual arrangement of the base .and intermediate units, the flanges of the units 16 having the` recesses 25 are seated in the notches 14 of the members 15 with the bodies of the base members registering with the said recesses.

Then a pair of the other intermediate units 17 are crossed over the ends of the previously positioned members 16, the ends with the recesses 29 being seated in the notches 22 of the member 16 with the flanged parts between the vnotches 22 entering the under channel of the Vunit 17 between the flanges of the latter having the recesses 29. In this relative position of the two members 16 and 17, the recessed flange parts 24 of the member 17 are seated in the notches 22,

Vt-he shoulders at the ends of the recesses 24 extend downward outside of the member 16. In thls Way, successive pairs of the intermediate units are alternately positioned until the desired height of the structure is obtained. On the top pair of intermediate units, as the uppermost units 17 in Figs. 1

and 2, is placed a pair of crowning units' 18. Each o/these units comprises an iron with a single channel and the ends of the langes j These parts are securely interlocked to withstand lateral strain and the superimposed members are capable of withstanding the crushing force of heavyweight. To add to the stability of the structure, the interior space is lled with concrete 31, 'and the spaces between the channel irons which are of a cell-like formation, are also filled with concrete 32. In placing the concrete 32, the upper channel of a unit is heaped full ofthe concrete, as shown in Fig. 6. lThe unit to be positioned above is then forced downward on the heaped concrete, which fills the under channel of the upper member and the surlus material is forced outwardly as the anges come together.

For some .purposes it may be desirable to.

give tothe support a shape other than rec- .tangular, hexagonal or octagonal for in- Astance. To provide such shapes, the notches and recesses in the flanges of the engaged v members are cut' diagonally across the same,

as indicated in Fig. 11. v

In the construction of bulkheads, where -the walls of the casings have considerable length, the length of the channel irons in one v directionl may be elongated4 to extend across severa of the spaced channel irons extend- 1 Y ing in the other direction, as shown in Figs. 12 and 13. Here, the abutting ends 33 of the extended units are positioned with relation to aI cross member, so that one of the ianges of the cross member engages one of the abutting ends and the other flange engages the other abutting end so as to a rigid connection between the a utting ends, as shown in Figs. 12 and 13.

What I claim is: Y
